crusher head 55 which in conjunction with the concaves 9 which line shell 1, coact in the well. known manner to crush the material put into the crusher.

l i ith the shaft 41; is associated an eccentric 10 having an inner bearingsnrtace 11 cooperatin with the shaft and an outer bear :ing'stu-tace l2 cooperating with the outer bearing 13. The bearing 13 is supported by a member 14'. The bearing; supporting member 1a is in turn supported from the shell by a number of: strut members one of which, 1.9, is shown in Fig. 1. The member 14 is in addition supported as appears in the parent application, supra, to resist the great strains put upon it by the eccentric when the crusher is in operation.

The eccentric has a bevel gear operalively associated therewith, as by means of the key E21 and the weight of this gear and the eccentric are carried by a wearing ring 22. The wearing. ring 22 is supported by a bottom plate 23 which may be bolted to and supported by the bottom shell. of the crusher. "lhe bottiun plate is here shown as provided with. a transversely extending flanged port on 24 for supporting the wearing ring; 22 and a transversly extending flanged portion by means oi? which the bottom plate may be fastened to the bottom shell.

The gear 20 is provided with a cover plate 526 which has a downwardly opei'iing; central recess 27 with which communicate radial passages 28 having openings 29 in the upper side oil the plate. While two radial. passages "are here shown, any desired number may be utilized. The purpose of the recess and 'adial passages will be hereinafter set torth.

The gear 20 is here shown as driven by a bevel pinion 30 associated with a crusher driving; shaft 3].. This driving shaft is supported. by a b iaring 32, A pump 33 which may be of the rotary gear type is mounted in the housing); of the bearing 32. This pum p is provided with a shaft having ends 34., 35 extending in opposite directions out off the casing of the pump. A. pinion 36 adapted to be keyed to either the end 34; or the end of the pump shaft. The pinion 3G is here shown a gear it? rigidly associated with "he lr'ivnig shaft- 1. 'llhe pump easier provided with ucylindrical portion 38 adapted to be journaled in a hole 39 in a wall 40 forming part of the bearing housing. The other end of the pump casing projects through a hole 41in a wall 42 also a portion of the bearing housing. The walls 42 are surmounted by a roof 43 which together form a housing for the pump. The end of the pump casing which projects through the wall 42 is provided with a flange 44 having holes 45 through which stud bolts are adapted to pass into the wall 42 whereby the pump may be'fastened. The suction side of the pump is connected by means of a pipe 46 through the wall 25 of the bottom plate to the annular well formed by the transverse portions or walls 24. 25 of the bottom plate and the gear 20. The discharge side of the pump is connected by means of a pipe 47 to the central portion of the bottom plate so as to -communicate with the oil well formed by the central portion of said plate.

In order to. prevent entrance of dust and other forei n material into the eccentric bearing surfaces and the lubricating oil, abonnet is provided. This bonnet is provided with a cylindrical portion 76 in- :ternally telescopically associated with the eccentric 10. The bonnet is provided with a transverse flange 77 extending over the 'outer bearingmember 13. The outer hearing membermay, to the end that the entrance of. foreign material will be more effectually prevented, be also provided with an inwardly extending flange 78. In order to prevent th entrance of foreign material between the cylindrical portion of the honnet and the crusher shaft 4, a dust ring 79 surrounding the said shaft 4 is provided and is formed to extend over said cylindrical portion 76. The bonnet may be rigidly associated in any desired manner with the eccentric and is preferably not in frictional ngagement with any of the associated parts, thus reducing wear.

1 In order to" provide for the passage of oil as between the inner and outer bearing surfaces 11; 12 of the eccentric any nuniber of oil passages 80, 81 may be provided. In order to provide for any excess of oil at the upper end of the eccentric and to prevent the overflow thereof onto the bearing support 14, the overflow pipe 82 is provided. The upper end of the pipe passes through th'e upp'er end of the outer bearing 18 and the lower end passes through one of the struts 19 where any oil passing through said pipe is discharged onto the surface of the gear 20.

' The operation, of the lubricating system as related to the illustrated crusher is as follows:

The rotation of the crusher driving shaft apredetermined direction causes the operation 'ofwthepump 33 by means of the,

gear 37 and the pinion 36. It may be stated that the direction of rotation of the pinion 36 should always be the same. the pump being of the gear type and irreversible. The operation of the pump causes oil to be drawn through the pipe 46, through the pump, and forced through the pipe 47 into the well formed by the central portion of th bottom plate Some of this oil forced up and out between the wearing ring 22 and the gear 20 thus affording eflicient lubrication for these parts. The major portion of the oil pumped into the central oil well passes into the recess 27 and as the cover plate 26 is being rotated by the gear the oil in question will be thrown out through the passages 28 by centrifugal force and will be expelled from the openings 29. The pressure of the centrifugal pump will thus be added to that of the gear pump and oil emerging from the openings 29 will be forced between the crusher shaft and the inner bearing 11 of the eccentric. up be tween these surfaces to and through the passages 80, 81, down between the outer bearing surface of the eccentric and the bearing 13, into the gear 20. The inside of the gear 20 will ordinarily not be filler] with oil inasmuch as the latter will be thrown up on the inside surface of the gear by centrifugal. force and from thence over the top thereof. From there the oil drops into the annular well formed by the transversely extending walls 24, 25 from where it again enters the pipe 46. If the space at the top of the outer bearing surface of the eccentric and the bearings 13 should become full of oil, the excess will be discharged through the pipe 82 onto the gear 20. as has already been pointed out. g It is desirable that it be possible, for vari ous reasons. to change the direction of rotation of the crusher driving shaft. Inasmuch as the shaft of the pump 33 mustro tate in the same direction, means must be provided whereby this result may be attained when the direction of rotation of the shaft 31 is reversed. The hereinhefore described mounting for the pump 33 provides a means whereby the direction of rotation of the pump may be readily kept the same. It is only necessary to remove the pinion 36, take out the stud bolts passing through the holes 45 into the wall 42, loosen the pipe connections 46. 47 a predetermined extent, and then rotate the pump 180 degrees so that the end 35 of the pul'np shaft will assume the position of the end 34 as viewed in Fig. 3. The pinion 36 is then keyed to the end 35 and the stud bolts for holding the pump in position are replaced. The pump is then in the proper relation to the shaft 31 so that the latter may be rotated in the reverse direction. The particular mounting of pump 33 is illustrative and it Ill) in case the .ltllliil 33 tails to ooerate tor a. I (my reason, the centrr l pinup lioruu-d in the cover plate illl is i e sutlicient pressure to lulu'icae the cot itric at least to such an extortv as to prevent damage to the rotating parts should the crusher continue in operation. If the centritugal pump is at suliicient strength to raise oil up to the top oi. the inner eccentri surface it this oil will pass throiu h the passages 80, 81. and as beiore described will reach the annular Well formed by the walls 524i, inasmuch, however, as no oil being drawn into the pipe it) the excess oil finds its way into the central well 23 between the Wearing; ring and the gear 20.

The connection of the rotary pump 33 and the centrifugal pump 26 in series whereby they may assist each. other in normal opcration. is a considerable factor in. l?lol.'GttSlH,t the reliability of the lubricating system inasmuch as, should the rotary pump tail, the

centrifugal pump which it is practically impossible to put out of operation, will :lurnish sufficient lubrication to prevent damage to the crusher, although of course, ordinarily the lul rication by the centrifugal pump alone mcy not be quite so etiicient as when the system operates normally.
